android, button help

Hello, all
I have a question about a button.
I have made a script for a button, but it doesnt work.
When i wana touch the button it has to go to the next scene.
What function do i have to use then?
I know how to make it go to the next scene.
Ty, already.

If this is a GUI button then

if(GUI.Button("x")) {
    Application.LoadLevel("whatever");
}

If this is a 3d object then:

  • Add a box collider

  • Write a function OnMouseDown() in the attached script

    function OnMouseDown() {
      Application.LoadLevel("whatever");
    

    }
